I feel the problem is for the past 30 years or more, people have been drip fed a philosophy of distrusting of anyone in a position of authority. This has been amplified by many branches of the news media turning into "news entertainment" and feeding their audience versions of the news that their readers / viewers want to see.
The result is if a person in some position of authority states something and someone else disagrees, their response is not to argue a counterpoint but rather to imply some form of conspiratorial behaviour: E.g.
Climate Scientists = Grant money whores
Teachers = Socialist / Gay / Atheist indoctrinators
Pastors etc. = Charlatans preying on the weak
Medical Profession = Cashing in on COVID
Government Initiative = Suppression of freedom
FBI et al = Agents of government domination
Mass killings etc. = False flag operations
BLM etc. = Front for Antifa / Communist insurgency
Tea Party etc. = Front for neo-Nazi organisations
Politicians = Traitors who hate America
By framing anything that does not fit the individual's world view as some form of evil there is no requirement to produce a counter argument or even consider the proposal. It is evil - end of story. In this sense it is not surprising people like Alex Jones find a following.
